Abstract
Sending and receiving of information between a coinmech control section performing controls relating to receiving and paying out of coins and a vendor control section performing controls relating to selection and vending of an article are made under the leadership of the vendor control section. Multiple kinds of information to be sent and received are previously classified into a plurality of modes and a mode including necessary information to be sent and received is designated on the side of the vendor control section by a mode selection code. Responsive to contents of the mode selection code, one of the coinmech control section and the vendor control section is brought into an information sending state and the other into an information receiving state whereby a group of information for this mode is sent and received.
